BiomX Inc. (now Tessera Defense) Announces 1-for-10 Reverse Split and Name Change

What Happened

• The company formerly known as BiomX Inc. filed amendments to its charter to effect a one-for-ten reverse stock split of its common stock and to change its name to Tessera Defense and Homeland Security Inc.
• The reverse split became effective at 12:01 a.m., Eastern Time, on September 9, 2026; the name change became effective at 12:01 a.m., Eastern Time, on September 11, 2026. The company’s common stock began trading on the NYSE American on a split-adjusted basis on September 9, 2026 and under the new name and ticker “HLSQ” at market open on September 11, 2026 (previous ticker: PHGE). New CUSIP: 09090D608.
• The company filed a press release and updated corporate presentation on September 15, 2026 (furnished as Exhibits 99.1 and 99.2).

Key Details

• Reverse split ratio: 1-for-10 (effective Sept 9, 2026 at 12:01 a.m. ET).
• Name change: BiomX Inc. → Tessera Defense and Homeland Security Inc. (effective Sept 11, 2026 at 12:01 a.m. ET).
• New trading symbol: HLSQ (began trading under new name/symbol Sept 11, 2026); prior symbol: PHGE. New CUSIP: 09090D608.
• Company issued a CEO letter and updated corporate presentation on Sept 15, 2026 (available on the investor relations website).

Why It Matters

• The reverse split reduces the number of outstanding shares and increases the per-share trading price proportionally; it does not change shareholder ownership percentages or rights. No action is required by stockholders.
• The name and ticker change reflect the company’s rebranding and may affect how investors track the stock (new ticker HLSQ and CUSIP). Trading continuity on the NYSE American was maintained through the transition.
• Investors should note the filing of the CEO letter and updated presentation for management’s messaging and strategic context; review those materials for any updates on business direction or plans.
